ABSTRACT

A system and method are provided for receiving navigational data via a wireless messaging service on a navigation system. The system and method provides a way to send requests for destination information via the wireless messaging service and capture navigational data from the responsive message received, such as addresses, telephone numbers, or email addresses, and then utilize that data for navigational routing, generation of telephone calls, emailing and the like, from the vehicle&#39;s navigation system. A wireless device can be paired with the navigation system over a Bluetooth communication link, wherein the navigation system periodically polls the wireless device for newly received messages. In one embodiment, the NAVI displays icons on a map that correspond to the extracted addresses from the messages received in relation to the vehicle&#39;s current location. The icons can be shown in a plurality of visual formats to distinguish previously viewed locations from newly received ones.

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority pursuant to 35 U.S.C. §119(e), to U.S.Provisional Application No. 60/837,406, filed Aug. 11, 2006, whichapplication is specifically incorporated herein, in its entirety, byreference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

A system and method are provided for receiving navigational data via awireless messaging service on a navigation system. More particularly,the system and method provide a way to receive as well as requestdestination information via the wireless messaging service and capturenavigational data from the message received, such as addresses,telephone numbers, or email addresses, and utilize the data fornavigational routing, the generation of telephone calls, emailing andthe like from the vehicle's navigation system.

2. Description of Related Art

Currently, when a user in a vehicle wishes to enter a destinationaddress into an onboard vehicle navigation system for routing to theaddress, the user must manually enter the address information directlyinto the user interface of the navigation system. Conversely, when auser wishes to place a telephone call using a Hands Free Telephone(“HFT”) device, the user can vocalize the desired telephone number anduse simple voice commands (e.g., “Call home” or “Check voicemail”),though there sometimes is a keypad or a set of buttons that allow manualentry of data. Manual entry of data, especially non-numeric text intothe navigation system is both cumbersome and time consuming.

The use of messaging services such as Short Message Service (“SMS”) totransmit and receive messages on mobile devices has gained in popularityand SMS use is ever increasing. SMS is a wireless messaging service thatenables the transmission of alphanumeric messages between mobilesubscribers and external systems such as electronic mail, paging, andvoice mail systems. Common usages for SMS messaging include, but are notlimited to: exchanging short messages; receiving email service over SMSsuch that messages delivered to that email address are converted toshort messages and delivered to a mobile device; receipt of informationservices like news, weather, entertainment, points of interest (“POI”),advertisements; and mobile chatting. Sending SMS messages in a vehiclefrom a handheld cellular phone can be difficult. Thus, it would bedesirable to have a way to simplify for the driver the process ofsending and receiving SMS messages from a vehicle.

Oftentimes, SMS messages received on a mobile device (e.g., a cellulartelephone) contain address data, telephone numbers, email addresses, orother navigational information that could be utilized by an onboardvehicle navigation system. Further, an SMS message may contain multiplesets of addresses and telephone numbers. This often occurs in responseto a user's request to an SMS service provider for a point of interestin the vicinity of the user's present location. Unfortunately, there iscurrently no method for capturing and synchronizing the telephone numberand navigational data obtained directly from the SMS message in theuser's mobile device to prevent the need for manual entry of theinformation into a vehicle navigational system by the user and to avoidduplication of information entries.

Existing navigational systems often use icons on a map screen toindicate to the user the desired location they wish to route to inrelation to the user's current location. The icons can take the form ofsimple geometric shapes like circles or diamonds or may be shaped likethe particular type of business they represent (e.g., shaped like agasoline pump for a gas station). These icons generally representlocations that are stored on a non-updated storage medium in thenavigational system, such as a DVD ROM. If a vehicle user requestsadditional Points of Interest information (e.g., address information)via SMS messaging on her phone, the responsive SMS messages received cancontain new addresses that might be represented by icons on the mapscreen. Accordingly, there is a need for a way to distinguish the iconsfor the newly received address information from the icons that arealready shown on the navigation screen (e.g., icons representinglocations from the DVD ROM and locations initially received from theuser's phone via SMS messaging).

SUMMARY OF THE INVENTION

The present invention addresses the shortcomings of the prior art systemand methods. In particular, the present invention is directed to asystem and method for sending and receiving wireless messages from SMSservice providers that can include a common short code (“CSC”) service(such as Google or Yahoo!). The system periodically polls a wirelessdevice for newly received messages at fixed or varying rates and canextract and save telephone numbers and addresses to an onboard vehiclenavigation/telematics system (“NAVI”) that can route to the extractedaddresses and/or call the extracted phone numbers via a wireless mobiledevice. The wireless device can be paired with the NAVI over a Bluetoothcommunication link, though other communications methods and protocolsare also within the scope of the invention. The user can also sendpredetermined reply messages from the NAVI in response to SMS textmessages received from the wireless device (e.g., a cellular telephone)and passed on to the NAVI.

In one embodiment, the NAVI displays icons on a map that correspond tothe extracted addresses from the messages received in relation to thevehicle's current location. The icons can be shown in a plurality ofvisual formats (e.g., icons comprising various colors and shapes) todistinguish previously viewed locations from newly received ones. Inanother embodiment, the system can pair-up address and telephoneinformation that correspond to a particular location in a receivedmessage when multiple locations have been returned by a CSC serviceprovider in response to a message request sent by the user.

In accordance with another aspect of the embodiments described herein,there is provided a method for displaying a new address in a “Pop Up”screen when the vehicle ignition switch is first set to the “Engine On”position, so the address will be easily selectable. The new address isdetermined be comparing the addresses that were previously stored to theones currently stored and showing the difference.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A method and system is provided for receiving navigational data via awireless messaging service on a navigation system. The term“navigational data” is used to mean any address, telephone number, emailaddress, IP address, longitude and latitude coordinates, or any othernavigational identifier yet to become commonplace for use on anavigation system for routing, calling, or the like. By parsing througha received message (e.g., an SMS message) containing navigational data,the data can be captured and stored for use by a navigation device orHFT for routing, the generation of telephone calls, emailing and thelike. It should be appreciated that the system and method is not limitedto the receipt of SMS messages, but would be equally applicable to thereceipt of messages utilizing any wireless messaging technology such asSimple Mail Transfer Protocol (“SMTP”) over Transmission ControlProtocol and the Internet Protocol (“TCP/IP”), Enhanced MessagingService (“EMS”), Multimedia Messaging Service (“MMS”), or the like. Inthe detailed description that follows, like element numerals are used todescribe like elements illustrated in one or more of the figures.

FIG. 1 provides a block diagram of an exemplary system 10 for receivinga message containing navigational data. The system 10 comprises a mobiledevice or wireless communication device or wireless device 12, a HandsFree Telephone 14, a navigation device (“NAVI”) 16, an audio module 18,and a NAVI display 20. The mobile device 12 may be a cell phone, PDA, orany mobile device known in the art that can receive messages such as anSMS message. The system 10 is located in a vehicle in a preferredembodiment of the system and method but should not be limited thereby.The mobile device 12 communicates with the HFT 14 such that theconnection between the mobile phone and the HFT may be via a serialcable, a Bluetooth link, an infrared link, or any other type of datacommunication connection known in the art. In the embodiment shown inFIG. 1, the mobile device 12 and the HFT 14 are equipped with a RadioFrequency (“RF”) transceiver (not shown) that complies with theBluetooth wireless data communication standard and protocol establishedby Bluetooth SIG, Inc. or the like, to allow communication andtransferring of messages between the two devices. In a preferredembodiment, the mobile device 12 and the HFT 14 are also equipped with aDial-Up Networking (DUN) profile that provides a standard to access theInternet and other dial-up services using a Bluetooth connection, aswell as supporting SMS commands. One of skill in the art will recognizethat the mobile device 12 can also establish a wireless Internetconnection by other communication methods such as broadband access overa Code Division Multiple Access (“CDMA”) cellular network.

The HFT 14 is in electrical communication with the NAVI 16, which inturn is in electrical communication with both the audio module 18 andthe NAVI display 20. The HFT 14 transfers messages and commands betweenthe mobile device 12 and the NAVI 16. The NAVI 16 acts as the mainonboard computer for the navigational system and connects all thecomponents of the system together as well as performs all routingcalculations and the generation of telephone calls via the HFT 14. TheNAVI 16 comprises a Global Positioning Satellite (“GPS”) receiver 2, aposition detection unit 4, a processor 6, a memory unit 8, and anintelligent text recognition system software component 9 thatdistinguishes navigational data such as address and telephone numbers ina message. The GPS receiver 2 receives satellite broadcast signals fromthree or more GPS satellites orbiting the earth. The position detectionunit 4 is operatively coupled to the GPS receiver 2 and can compute thecurrent longitude and latitude coordinates of the vehicle usingtrilateration. The processor 6 can be operatively coupled to the memoryunit 8, the GPS receiver 2, and the NAVI display 20. The memory unit 9can comprise executable code that allows the processor to performvarious functions such as running the intelligent text recognitionsoftware or instructing the NAVI display 20 to calculate travel routesand to display particular images (e.g., maps and routing information).The NAVI display 20 acts as a visual interface to the user and can be atouchscreen that allows for both the display of data as well as actingas the user interface for entry of information into the NAVI 16. TheNAVI 16 can include an optional text-to-speech (“TTS”) engine orsoftware component that interfaces with the audio module 18 to allowmessages to be read to the user in an auditory format. The NAVI 16 mayadditionally include a human machine interface (“HMI”) for displayingmessages and available commands via the NAVI display 20 and receivingentries from the user by incorporating a touchscreen into the NAVIdisplay or by use of buttons, a keypad, a microphone interconnected to avoice recognition (“VR”) system, or the like.

In a preferred embodiment of the system and method, the mobile device 12is queried every fifteen seconds via the HFT 14 to determine if a newSMS message has been received, but it should be appreciated that othertime intervals can be utilized as well. If an SMS message is present,the SMS message is transmitted to the NAVI 16 for storage and can bedisplayed on the NAVI display 20. It should be appreciated that eachcomponent of the system can be integrated together as one hardwaresystem onboard the vehicle or can be utilized as separate components. Inanother embodiment, the NAVI 16 can be equipped with an RF transceiver(not shown) that complies with the Bluetooth wireless data communicationstandard and protocol, wherein the NAVI 16 can communicate directly withthe mobile device 12 to allow communication and transferring of messagesbetween the two devices without the use of the HFT 14.

The mobile device 12 can act as a Mobile Station (“MS”) and may send orreceive SMS messages to and from a Mobile Switching Center (“MSC”)located in wireless proximity to the mobile device 12. The MS comprisesall user equipment and software needed for communication with a wirelesstelephone network. The MSC acts as a telephone exchange that providescircuit-switched calling, mobility management, and services such asvoice, data, fax, as well as SMS to mobile phones roaming within thearea that the MSC serves. Additionally, in another embodiment, themobile device 12 can be replaced with an SMS transceiver (not shown)that is located within the NAVI 16, so that the NAVI 16 can directlyreceive and send SMS messages.

FIG. 2 shows an exemplary embodiment of a system for receiving an SMSmessage 21 on a mobile device 12 and utilizing the telephone number andaddress data contained in the received SMS message 21 in a vehiclenavigation system for the placement of a telephone call and for addressrouting. In the embodiment, an SMS message 21 may be entered into adevice or computer capable of supporting SMS message generation. The SMSmessage 21 is addressed to the mobile device 12 user and comprises bothan address and a telephone number in the text of the message. The SMSmessage 21 is subsequently transmitted over the wireless network 22(e.g., a Global System for Mobile Communications (“GSM”) network or aCDMA network) and is received at the mobile device 12. The mobile device12 and the user are both located in the vehicle 30 in accordance withthis embodiment. After the SMS message 21 is received, the NAVI display20 in the vehicle 30 indicates that a new SMS message 21 has arrived. Itshould be appreciated that the SMS message 21 may be received at anytime by the mobile device 12, even when the user is not located in thevehicle. When the user enters the wireless proximity of the vehicle withthe mobile device 12, the NAVI 16 may automatically retrieve new SMSmessages 21 from the mobile device 12, as well as periodically pollingthe mobile device 12 for newly received messages. The user can thenselect the SMS message 21 to be read aloud via the TTS softwarecomponent 26.

The intelligent text recognition system in the NAVI 16 detects addressesand telephone numbers in the SMS message and enables the route and callfunctions via the HMI accordingly. If no addresses or telephone numbersare detected, the route and call functions are disabled. It should beappreciated that the SMS message 21 may comprise any number ofaddresses, telephone numbers, email addresses and the like, and each onewill be detected by the intelligent text recognition system. In additionto having the SMS message 21 read aloud, the user can request routing tothe address contained in the SMS message 21 by selecting a travel routeor route function via the HMI. When routing is requested by the user,the NAVI 16 calculates a route based at least in part on the currentlocation of the vehicle, to the address 24 contained in the SMS message21 and displays a map 25 with the suggested route highlighted (e.g., bythe use of arrows and lines of varying density and colors).Additionally, the user may wish to place a telephone call to the phonenumber contained in the SMS message 21 by selecting a “Call” functionvia the HMI. A call can be placed via the HFT 14 using the telephonenumber 28 detected in the SMS message 21.

FIG. 3 shows an exemplary embodiment of a system for the generation ofan SMS POI request message 40 from a mobile device 12 that utilizes thenavigational data in the received SMS message response 34 in a vehiclenavigation system. In the exemplary embodiment, an SMS request message40 is sent to an SMS POI service such as a Common Short Code servicethat includes multiple SMS service providers like Yahoo! and Google.Information searches can be requested on a particular subject, company,etc. For example, the SMS request message 40 may request all coffeehouses in a specific city and state. It should be appreciated that anyPOI messaging service may be used. The SMS request message 40 is enteredvia an HMI link to the NAVI 16, located in vehicle 30. The user canenter information, such as company name, city, state, longitude,latitude, zip code, or the like. If a specific location is not selectedby the user, the SMS request message 40 may be generated using locationinformation retrieved via the GPS receiver 2 (see Fig. see FIG. 1)connected to the NAVI 16 in the vehicle. The SMS request message 40 isthen transmitted via a wireless Bluetooth connection to the mobiledevice 12 of the user. The SMS request message 40 is addressed to thePOI SMS message service provider 32 and is subsequently transmitted overthe wireless network 22 (e.g., a GSM or CDMA network). The SMS requestmessage 40 is received at the POI SMS message service provider 32 thatautomatically generates an SMS response message 34 that is transmittedback to the mobile device 12, via the wireless network 22. In responseto the request message 40, the text portion of the SMS response message34 may comprise both an address and a telephone number for the requestedPOI.

The NAVI display 20 in the vehicle 30 indicates when a new SMS message36 has arrived. It should be appreciated that the SMS message 36 may bereceived at any time by the mobile device 12, even when the user is notlocated in the vehicle. When the user enters the wireless proximity ofthe vehicle with the mobile device 12, the NAVI 16 may automaticallyretrieve the new SMS message 36 from the mobile device 12 at that time,as well as periodically polling the mobile device 12 for newly receivedmessages. The user may then select the SMS message 36 to be read aloudvia the TTS software component 26. The intelligent text recognitionsystem in the NAVI 16 detects both the address and the telephone numberin the SMS message and enables the route and call functions on the HMI.If no address or telephone number are detected, then the route and callfunctions are disabled. It should be appreciated that the SMS message 36may comprise any number of addresses, telephone numbers, email addressesand the like and each one will be detected by the intelligent textrecognition system. The user may route to the address contained in theSMS message by selecting a route function via an HMI. The NAVI 16 thencalculates a route to the address contained in the SMS message 36.Additionally, the user may place a telephone call to the phone numbercontained in the SMS message 36 by selecting a call function via theHMI. A call is then placed via the HFT 14 using the telephone numberdetected in the SMS message 36. In an alternate embodiment of the systemand method, the NAVI 16 may automatically route to the address locatedin the received SMS message rather than first requiring selection of therouting function by the user. A POI icon may be used to indicate thelocation of the extracted address on the routing map displayed.Additionally, the NAVI 16 may automatically store the extractedaddresses and/or phone numbers in an Address Book stored on the vehicle.In an embodiment of the system and method, a timer (not shown) may beimplemented in the NAVI 16, such that an error message may be displayedif the timer expires and an SMS response message 36 has not yet beenreceived.

FIG. 4 is a flow diagram of an exemplary method of retrieving andsending SMS messages with a wireless mobile device and a Bluetoothenabled NAVI according to an embodiment of the system and method. Thecommunication utilized for receiving and sending SMS messages betweenthe wireless device 12 and the HFT 14 occurs in five modes-namely,Initiate Mode 42, Ready Mode 44, Expectant Mode 48, Reply Mode 56, andOff Mode 64. FIG. 4 is a high-level diagram that shows how the fivemodes interact with each other. Details of the operation of each modeare illustrated in FIGS. 5A-E and described in detail below.

In FIG. 4, the algorithm begins in the Initiate Mode in step 42. There,all messages residing in the wireless device 12 are retrieved by the HFT14 just after the vehicle ignition is set to the “ON” or “ACC” (i.e.,Accessory) position (the normal mode of operation for the system andmethod) and a link between the wireless device 12 and the HFT 14 areaffirmatively linked with each other via a Bluetooth connection. Oneskilled in the art will recognize that in other embodiments other radiostandards, communication protocols, and other type of data communicationconnections known in the art (e.g., an infrared link) can be utilized toestablish a two-way communications link between the wireless device 12and the HFT 14. Once the communication link between these two devices isestablished, the algorithm proceeds to step 44 where the system entersthe Ready Mode.

In the Ready Mode, the NAVI 16 periodically polls or checks for newlyreceived messages by communicating with the HFT 14, which in turncommunicates with the wireless device 12 using the Bluetooth connection.The system is capable of sending message requests and replies composedin the vehicle using the NAVI Display 20 or other HMI devices (such as akeypad or keyboard or a voice recognition system) to the wireless device12, using the Bluetooth connection. If a message request is composed andsent in step 46, then the system exits Ready Mode and enters theExpectant Mode in step 48. If the expected message is received within anallotted amount of time in step 50, then the message is sent to the NAVIto process in step 52. If the allotted amount of time expires before theexpected message is received, then the NAVI displays an error message(and in another embodiment, audibly notifies the user of the errorcondition).

A reply message can be sent to the source of the SMS message if thesystem received a message in the Initiate or Ready Mode at step 54 andthe system determines (from the phone number of the sender of the SMSmessage), that the message is a personal message (as opposed to amessage sent from a CSC service provider). That is, the system checksthe sender's phone number to determine if it is a valid phone numberfrom other than a CSC service provider and if so, enables the “Reply”button on the NAVI display 20. The Reply button can also be located onother HMI devices such as a keypad or keyboard in the vehicle. When theReply button is selected by the user, the system enters the Reply Modein step 56. The user can choose from a variety of preset reply messagesin step 58. The user selects an appropriate reply message and a “Send”button is selected on the NAVI display 20 (or the Send button can belocated on a keypad or keyboard in the vehicle). The system then exitsthe Reply Mode and returns to the Ready Mode after the HFT 14 confirmsthat the message was successfully sent to the mobile device 12. The NAVIdisplay 20 will show that the message was sent successfully.

During the Expectant Mode, in step 48, the system is waiting for orexpects the receipt of a return message by the wireless device 12 inresponse to the in-vehicle message request sent in step 46. The systempreferably increases the polling rate to the wireless device 12 so thatany newly received messages are detected by the system soon after themessages are received by the wireless device 12. In another embodiment,the system, in step 50, examines messages received to determine if theyhave been sent from the expected same phone number as the messagerequest has been sent to. If so, the system determines the receivedmessage to be in response to the message request sent by the user. Themessage is then sent to the NAVI 16 to process further (e.g., to notifythe user and transfer to the NAVI Inbox (see FIG. 11B)) in step 52. Ifthe message received is not determined to have been sent in response tothe message request sent previously, the system remains in the ExpectantMode and the algorithm returns to step 48 where the system remains untila timed-out condition occurs, as described with respect to Step 50,above.

Continuing with the Reply Mode in step 56, the user can select a presetor pre-composed SMS message in reply to a received message. In step 58,the selected reply message is sent by the NAVI 16 to the HFT 14 that inturn communicates the reply message with the wireless device 12. Thewireless device 12 ultimately transmits the reply message to a remotelocation such as a friend's phone. The algorithm then returns to step44, where the system exits the Reply Mode and again enters the ReadyMode.

At step 60, the HFT 14 checks if the wireless device 12 is stilldetected. If yes and the power has not been turned off, at step 62 thesystem remains in the Ready Mode. If the Bluetooth wireless device 12 isno longer detected at step 60, the system exits the Ready Mode andenters the Off Mode in step 64. In the Off Mode, the system stopspolling the wireless device 12 for new messages. If a Bluetooth phonesuch as the wireless device 12 or another compatible device is detected,the algorithm returns to step 42 where the system exits the Off Mode andenters the Initiate Mode. If the vehicle ignition is no longer in the ONposition, as determined in step 62, the system enters Off Mode.

When the ignition is first set to the ON position, the system detectsthe mobile device 12 and the system starts the Initiate Mode process(e.g., the bonding operation). On the other hand, if the ignition switchis still in the ON position (as determined in step 62), but the systemhas merely lost communications with a Bluetooth wireless device, in step60, the system can immediately proceed with establishing a link with thenewly detected wireless device in step 42, starting the Initiate Modeprocess.

FIGS. 5A-E illustrate different aspects of a more detailed flow diagramfor the exemplary method of retrieving and sending SMS messages usingthe wireless mobile device 12 with the Bluetooth enabled NAVI 16, as wasdiscussed with respect to FIG. 4, above. FIG. 5A illustrates thedetailed steps of the algorithm for the Initiate Mode. The vehicleignition switch has been turned on (set to the “ON” or the “ACC”position) in step 68. Entry point A, as shown in block 69, is providedto allow other portions of the routine to return to this starting point.The system then establishes a two-way communications link between thewireless device 12 and the HFT 14 in step 70. The HFT 14 sends AT(attention) commands (which are part of the Hayes command set of modemcommands) to the wireless device 12 to set the device to the ProtocolData Unit (“PDU”) mode.

If an error message is received by the HFT 14 or the wireless device 12does not respond within a predetermined time to the AT commands sent instep 74, then the system proceeds to step 76, where the system sendsadditional AT commands instructing the wireless device 12 to enter the“Text” mode. If the wireless device does successfully enter the PDUmode, the algorithm proceeds to step 78. In either case, whether thewireless device 12 is in the text mode or the PDU mode, the system sendsAT commands to the device so the HFT 14 can retrieve the SMS messagescurrently stored in the wireless device 12 in step 78. The HFT 14receives the SMS messages in step 80 and preferably revises the messageformat before the message is communicatively coupled to the NAVI 16. Thesystem next exits the Initiate Mode and enters the Ready Mode in step 82via entry point B at block 81.

FIG. 5B illustrates the detailed steps of the algorithm for the ReadyMode. Entry point B, as shown in block 81, is provided to allow otherportions of the routine to return to this starting point. In step 82,the HFT 14 periodically sends AT (attention) commands to the wirelessdevice 12 (e.g., once every fifteen seconds) instructing the device totransmit any new SMS messages that have been received over the wirelessnetwork (not shown) from a remote location or service provider. In step84, the algorithm determines if the wireless device 12 has received anynew SMS messages (e.g., messages not yet retrieved from the wirelessdevice 12 by the HFT 14). If not, the algorithm returns to step 82 andthe system remains in the Ready Mode. If new messages have beenreceived, the messages are retrieved by the HFT 14 via the Bluetoothconnection link to the wireless device 12 in step 86 and are transferredto the NAVI 16. The retrieved SMS messages can be viewed by the user onthe NAVI display 20, and any telephone and address information in theretrieved message are extracted by the NAVI 16 for further processing instep 88. The processing can include making additions to the NAVI addressbook, showing locations as icons on a map, displaying routinginformation, reading the message via Text to Speech (“TTS”) and thelike.

Once the wireless device 14 has been bound with the HFT 14, the user cancompose an SMS message request (e.g., a request for information from aCSC service provider such as Google or Yahoo!) to be transmitted to aremote location or service provider by the wireless device 12. If theuser chooses to send a request message, the system will send themessages to the HFT 14 and to then on to the wireless device 12 in step90. Simultaneously, the system will proceeds to step 98, while thesystem exits the Ready Mode and enters the Expectant Mode via entrypoint C, at block 91. Similarly, the user can choose to reply to areceived personal text message from the Ready Mode in step 96. Thesystem exits the Ready Mode and enters the Reply Mode in step 108 viaentry point D at block 97.

The system continuously monitors for the presence of a wireless deviceat step 92. If the wireless device 12 is no longer detected, the systemexits the Ready Mode and enters the Off Mode in step 118 via entry pointE at block 93. If the Wireless device 12 is still detected, thealgorithm proceeds to step 94 and determines if the system has beenturned off (e.g., the ignition has been set to the “OFF” position by theuser). If so, the system exits the Ready Mode and enters the Off Mode instep 118 via entry point E at block 93. If on the other hand, the systemhas not been turned off, the system remains in the Ready Mode.

FIG. 5C illustrates the detailed steps of the algorithm for theExpectant Mode. Entry point C, as shown in block 91, is provided toallow other portions of the routine to return to this starting point. Instep 98, the system is waiting for or expects the receipt of a returnmessage by the wireless device 12 in response to the in-vehicle messagerequest sent at or before step 90 (see FIG. 5B). The system increasesthe polling rate (e.g., the transmission rate of AT commands sent fromthe HFT 14 is increased to a frequency of less than fifteen seconds) tothe wireless device 12 so that any newly received messages are detectedby the system soon after the messages are received by the wirelessdevice 12.

In step 100, the algorithm determines if the system has received a newSMS message. If a new message has not been received, the algorithmreturns to step 98 and the system remains in the Expectant Mode for aspecified amount of time. If a new message has been received, thealgorithm proceeds to step 102, where the system examines any newmessages received and extracts the “sent from” information. In anotherembodiment, the “sent from” information is compared to the “sent to”phone number or CDC provider code of the message request previously sentby the user. Using the comparison results, the algorithm determines ifthe newly received SMS message is the requested message response thesystem has been expecting in step 104. If so, the system determines thereceived message to be in response to the message request sent by theuser. The message is then sent to the NAVI 16 to process further (e.g.,to notify the user and transfer to the NAVI Inbox (see FIG. 11B)) instep 106. Next, the system exits the Expectant Mode and returns to theReady Mode in step 82 via entry point B at block 81. If in step 104, themessage received is determined not to be a response to the user'smessage request, then the system remains in the Expectant Mode and thealgorithm returns to step 98.

FIG. 5D illustrates the detailed steps of the algorithm for the ReplyMode. Entry point D, as shown in block 97, is provided to allow otherportions of the routine to return to this starting point. In step 108,the “send to” information for the reply message is retrieved from thepreviously received message so the user will not have to re-enter theinformation in formulating her reply message. The user selects a desiredpreset reply message from a list of available responses in step 110. Thepreset reply message can comprise “I am on my way,” “Yes, thanks,” “No,thanks,” “I'm driving,” “I'll talk to you later,” and the like.

In one embodiment, the user can select a desired message response byscrolling through various menus on the screen of the NAVI display 20. Inother embodiments, the user can select a desired preset reply messagefrom a list that is read aloud via the TTS software component 26 (seeFIG. 3). In a variation of this embodiment, the user can speak herchoice of available reply messages using voice recognition software thatis integrated into the NAVI 16 system. In step 112, the selected replymessage is sent by the NAVI 16 to the HFT 14 and the HFT 14 reformatsthe selected reply message. The HFT 12 then transmits the message to thewireless device 12 via the Bluetooth communications link. The wirelessdevice 12 in turn transmits the reply message to a remote location orservice provider via a wireless network (not shown). Next, the wirelessdevice 12 transmits a message to the HFT 14 confirming that the replymessage has been sent over the wireless network in step 114. A “messagesent” confirmation screen is then displayed on the NAVI display 20 instep 116. The system then exits the Reply Mode and returns to the ReadyMode in step 82 via entry point B at block 81.

FIG. 5E illustrates the steps of the algorithm for the Off Mode. Entrypoint E, as shown in block 93, is provided to allow other portions ofthe routine to return to this starting point. In step 118, the systemstops polling the wireless device 12 for new messages. If the user hasturned off her wireless device 12 or the batteries run low, the devicemay lose the communications link with the HFT 14 in step 92 (see FIG.5B). However, once a Bluetooth phone such as the wireless device 12 oranother compatible device (e.g., a device with a new Bluetooth ID) isdetected, the algorithm returns to step 70 via entry point A at block69, while the system exits the Off Mode and enters the Initiate Mode. Ifthe vehicle ignition is no longer in the “ON” Position, as determined bythe algorithm in step 94 (see FIG. 5B), the system enters the Off Mode.When the ignition is set to the ON position, the system will enter theInitiate Mode at step 70 via entry point A at block 69. On the otherhand, if the ignition system is still in the “ON” position, but thesystem has merely lost communications with the wireless device 12 instep 92, the system can immediately proceed with establishing a linkwith the newly detected wireless device in step 70 (see FIG. 5A). Thesystem simply enters Initiate Mode as if the algorithm was firstcommenced after the vehicle's ignition was set to the ON position instep 68. The system clears its memory, retrieves all SMS messages fromthe wireless device 12, and monitor for newly received messages.

FIG. 6 is a diagram illustrating two exemplary data formats for SMSmessages 122 and 124 received from two SMS message providers in responseto a user inquiry, according to an embodiment of the system and method.Data format 126 illustrates two possible data formats for the addressand phone number information contained in a received SMS message. Format1 corresponds to the format of the data contained in the SMS messages122. Format 2 similarly corresponds to the format of the data containedin SMS message 124. In FIG. 6, similar requests for the address andtelephone numbers for the nearest locations of a particular business,Eric's Coffee Shop, were requested via two separate SMS messages. TheSMS messages sent via the NAVI (not shown) contained the currentlocation of the user and were sent to two different CSC serviceproviders, though other types of service providers as well as othertypes of messaging services (e.g., multimedia messaging service), can beutilized with the invention.

SMS message 122 contains the address and phone number listings for twolocations of Eric's Coffee Shop that are located within a predetermineddistance or radius from the user's current location. The two listingscontain the business name followed by the address (street number, streetname, city, state, and zip code) and then the corresponding telephonenumber for each location in the SMS message. SMS message 124 similarlycontains the address and phone number listings for two locations ofEric's Coffee Shop within a predetermined radius of the user's location,but the phone number for each location of Eric's Coffee Shop appearsafter the business name, before the address information appears. SMSmessage responses from different CSC providers may return differentnumbers of business locations within the same predetermined distancefrom the user's location, depending on the particular algorithms usedand data stored in the CSC provider's databases. Format 1 of data format126 contains text characters followed by a first address, additionaltext characters followed by a first phone number for the first businesslocation. This format repeats for a second address and a secondcorresponding phone number for a second business location andsubsequently for as many business listings that are in the SMS message122. Format 2 of data format 126 contains text characters followed by afirst phone number, additional text characters followed by a firstaddress for the first business location. This format repeats for asecond phone number and a second corresponding address for a secondbusiness location and subsequently for as many business listings asthere are in the SMS message 122.

FIG. 7 is a flow diagram for a method of associating address informationwith telephone information contained in an SMS message according to anembodiment of the system and method. The system can associate theaddress information with the telephone information for a particularlisting contained in the received SMS message, whether the messagefollows format 1 or format 2 of data format 126 (see FIG. 6). If thedata in a particular SMS message does not match format 1 or format 2,then the address and phone numbers contained in the SMS message will bestored separately. One skilled in the art will recognize, however, thatthe method can be easily modified to recognize additional formats.

The algorithm or method illustrated in FIG. 7 operates as follows.First, the vehicle ignition is set to the “ON” position in step 128 andthe NAVI 16 retrieves an SMS message from a wireless telephone or mobiledevice 12 in step 130. Polling of the wireless device 12 is periodicallycarried out by the NAVI 16 to retrieve newly received SMS messages fromthe wireless device 12 (see FIGS. 4 and 5A-E; see also, relateddiscussion thereto). The intelligent text recognition system determinesif the received SMS message contains recognizable phone and addressinformation in step 132 (see FIGS. 12 to 14E for details of the methodof extracting and recognizing addresses and phone numbers).

If no address or phone number information is recognized in the receivedSMS message, the information received in the message is converted to thesystem's internal data format or onboard format in step 143 and thenstored in memory in step 144. If on the other hand, the address andphone number information are recognized, the system determines if theformat of the received SMS message matches format 1 of data format 126in step 134. If there is a match, the system associates the address andthe phone number for a particular listing with each other in step 136and the data is converted to the internal format used by the system instep 143. The converted data is then stored in memory in step 144. Ifthere is no match with format 1, the method proceeds to step 138 andsimilarly determines if the format of the received SMS message matchesformat 2 of data format 126. If there is a match, the system associatesthe address and the phone number for a particular listing with eachother in step 140, and the data is converted to the internal format usedby the system in step 143. The converted data is then stored in memoryin step 144. If there is no match with format 2, the method proceeds tostep 142, where the method determines that the address and phone numberinformation contained in the SMS message are to be stored separately inthe system memory and proceeds to do so by first converting the dataformat in step 143. The system then stores the converted data in step144. If there are additional messages received from the wireless device12 in step 146, the method returns to step 132 and the system once againextracts and recognizes addresses from the received SMS message;otherwise, the method ends.

In another embodiment, the system can recognize keywords in the text ofthe SMS message at step 132, that will identify the service provider andthereby identify the format to be used to help parse the address andphone number information from the SMS message received at step 130. Inyet another embodiment, the “sent from” number contained in the SMSmessage can be recognized at step 132, and then used to identify theservice provider; thereby identifying the format to be used to helpparse the address and phone number information from the SMS messagereceived at step 130.

FIGS. 8A-B are flow diagrams for an exemplary method of displayingdifferent colored location icons on a map to distinguish newly receivedaddress information from previously received address informationextracted from incoming SMS messages according to an embodiment of thesystem and method. In FIG. 8A, the vehicle ignition is set to the “ON”position in step 148 and the NAVI 16 retrieves all SMS message from themobile device 12 in step 150. In another embodiment, the NAVI 16 canretrieve all SMS messages from the HFT 14. Polling of the wirelessdevice 12 is carried out by the NAVI 16 to retrieve additional SMSmessages that are received by the wireless device 12 (see FIGS. 4 and5A-E and related discussion thereto). The intelligent text recognitionsystem determines if the received SMS message contains any phone andaddress information in step 152 (see FIGS. 12 to 14E for details of themethod of extracting and recognizing addresses and phone numbers) andextracts them. The method proceeds to step 154 where the systemdetermines if a corresponding entry for the extracted address is alreadystored in the internal file, which comprises a table, an array, adatabase, or other data structure. If not, the extracted address isdetermined to be a new address and is added into the internal file instep 158. The method next proceeds to step 160. If the extracted addressalready exists in the internal file, in step 156, the address isdetermined to be not new and the system does not add the extractedaddress to the Address Book, but instead, the algorithm bypasses step158, and proceeds to step 160.

By determining that the address is new in this way, the address can behighlighted in a “pop up” screen (appearing on the NAVI display 20 orother display screens located in the user's vehicle) or the user can beprompted by TTS to notify her that the NAVI 16 recognized that there isa new address in one or more of the SMS messages received. A new addressis likely to be of more interest to the user than a previously viewedaddress and allowing the user to easily route to the new address orplace a phone call to the phone number contained in the relevant SMSmessage, is believed to be a significant benefit to vehicle users. Inanother embodiment, the internal file can be an Address Book that isautomatically updated with the address it receives via the wirelessdevice.

In step 160, the extracted address is shown in a first visual format,such as an icon or location icon in a first color or priority color(such as red) on a map that can be displayed on the NAVI display 20 (seeFIG. 10A). The location icon comprises a first shape (such as atriangle). In another embodiment, the location icon is shown as a shadeddiamond on the embodiment of FIG. 10A, but the actual map image thatappears on the NAVI display 20 can comprise any visible color (orshading) and take any shape such as a circle, square or a complex shapesuch as a building (or even a particular type of building such as a gasstation or hotel). In step 162, the text message is added to the NAVIInbox (see FIG. 11B). Next, in step 164, the method checks to see ifthere are additional messages retrieved by the NAVI 16 from the wirelessmobile device 12. If so, the method returns to step 150 to retrieve theadditional message and again checks if there are addresses to extractfrom the additional retrieved SMS messages in step 152.

The algorithm shown in FIG. 8B depicts the case where: 1) the vehicleignition switch has been ON for a period of time and the NAVI 14 hasalready received and plotted (as a red location icon) one or moreaddresses as a result of completing the Initiate Mode, and 2) one ormore additional addresses have been received at a later time and thereis a need to distinguish the location of the newly received address fromthe previously received and plotted addresses. The operation of steps168, 170 and 172 are slightly different from steps 148,150, and 152 ofFIG. 8A.

In step 168, the vehicle ignition has been in the “ON” position for asufficient time period that at least one location icon of a first colorhas been shown to the user on a map on the NAVI display 20, inaccordance with the method of FIG. 8A. The system periodically polls thewireless device 12 over a Bluetooth connection with the HFT 14 for newlyreceived messages (see FIGS. 4 and 5A-E, and discussion thereto). Instep 170, the NAVI 16 receives a new SMS message from a wireless device12 and the intelligent text recognition system determines if the new SMSmessage contains any phone and address information in step 172. If not,the method proceeds to step 184; otherwise, the method proceeds to step174 where any location icons of the first visual format (that are of thepriority color since older addresses do not yet exist), generated fromone or more of the previously-stored addresses and shown on the map onthe NAVI display 20, are changed from the first visual format (the firstshape and the first color (priority color (such as red)) to a secondcolor or non-priority color (such as grey) and a second shape. Then, thenewly received address is plotted on the map in the priority color(e.g., Red). In this way, the most recently received addresses that isdifferent from the previously-stored address will always be shown withthe priority colored icons and the addresses previously received (olderaddresses) will be shown as icons of the second color or as non-prioritycolored icons (e.g., Grey) and the second shape. Next, the methodproceeds to step 176 to determine if a corresponding entry for theextracted address is already stored in the internal file that can beloaded into the memory unit 8 (see FIG. 1). If not, the extractedaddress is added to the internal file in step 180 and the methodproceeds to step 182. If the extracted address already exists in theinternal file, the system does not add the extracted address to theinternal file in step 178. Instead, the method bypasses step 180, andproceeds to step 182. As discussed above, in another embodiment, theinternal file can be an Address Book.

In step 182, the extracted address is shown in the first visual format,such as the icon or location icon in the first color (such as red) onthe map and can be displayed on the NAVI display 20 (see FIG. 10A). Thelocation icon comprises the first shape and the first color (such as ared diamond in the embodiment of FIG. 10A), but can comprise any visiblecolor and take any shape such as a circle, square or a complex shape. Instep 184, the text message is added to the NAVI Inbox (see FIG. 11B). Instep 186, the method checks if there are additional messages retrievedby the NAVI 16 from the wireless device 12. If so, the method returns tostep 170 to retrieve the additional message and again checks if thereare addresses to extract from the additional retrieved SMS messages instep 172.

In another embodiment, the algorithms depicted in FIGS. 8A-B can bemodified slightly so that phone number information extracted in step 152is shown in a first color (such as red) in step 160 on the NAVI display20. Similarly, when new phone number information extracted in step 172all previously-stored phone numbers (stored in the internal file and canbe loaded into the memory unit 8) initially shown in the first color orpriority color (such as red) are changed to a second color ornon-priority color (such as grey) in step 174. Next, newly extractedphone numbers that are different from the previously-stored phonenumbers, are shown on the NAVI display 20 in the first color (e.g. red)in step 182.

FIG. 9 is a flow diagram for an exemplary method of storing addressinformation from retrieved SMS messages while clearing map locationicons and NAVI Inbox text messages when the vehicle ignition is turned“OFF” according to an embodiment of the system and method. That is, whenthe user deletes a text message on her cell phone or wireless device 12(see FIGS. 1-3), the corresponding map location icons, and NAVI Inboxmessage listing (discussed with respect to FIGS. 8A and 8B, above) willcontinue to appear to the user until the vehicle ignition is set to the“OFF” position. At that time, the system will delete the location iconsand NAVI Inbox message listings that were deleted from the user's cell.In another embodiment, optional step 191 will be performed after step190 (described below) to delete the address information, unless the userelects to save it in the NAVI Address Book.

In step 188, the vehicle ignition switch has been set to the “OFF”position (e.g., the user turned off the engine and removed her key). Thealgorithm then proceeds to step 190 where internal file entries (notshown) contained in incoming SMS messages are deleted from the wirelessdevice 12 while the vehicle's ignition was in the “ON” position, afterthe vehicle ignition has been set to the “OFF” position. In step 192,all location icons that correspond to addresses extracted from retrievedSMS messages on the wireless device 12, wherein the original SMS messagehas been deleted from the wireless device 12, are deleted from the NAVImap on the NAVI display 20 when the vehicle ignition is set to the “OFF”position. The deletion of location icons includes both location icons ofthe first and second color. In step 194, all messages deleted from thewireless device 12 while the vehicle's ignition was in the “ON” positionwill in turn be deleted from the NAVI inbox when the vehicle ignition isset to the “OFF” position.

FIGS. 10A-B are examples of the NAVI display 20 showing maps of thecurrent vehicle position with differently shaded location iconscorresponding to addresses in received SMS messages according to anembodiment of the system and method. The actual image visible on theNAVI display 20, can however, comprise differently colored locationicons as well. In FIGS. 10A and 10B, location icons 196, 198, 200, 202,and 204 are visible. These location icons represent particular addresseson a map in relation to the current position of the user's vehicle.Current location icon 196 represents the vehicle's current location andthe position of icon 196 on the map will change as the NAVI displayscreen 20 is refreshed, if the vehicle has since moved. In FIG. 10 a,icon 196 is wing-shaped and is encircled to stand out from the otherlocation icons on the map, but can be shaped differently in otherembodiments, as well as comprising an icon that is of the same ordifferent color than icons 198-204. Location icons 198-204 are shown asdiamond shaped icons placed on the map in the location that correspondsto the address extracted from SMS messages retrieved from the wirelessdevice and listed in the NAVI inbox (not shown), but other shaped iconscan be utilized as well. The use of the location icons as well as howand when they change color have been discussed with respect to thealgorithms shown in FIGS. 8A and 8B, above.

Icons 198 and 200 comprise the second visual format that can comprisethe second color or non-priority color (e.g., grey) and can comprise thesecond shape. These icons depict older addresses and represent locationsextracted from SMS messages in the NAVI inbox that have been initiallyretrieved from the wireless device 12. Location icons 202 and 204 alsorepresent locations extracted from SMS messages in the NAVI inbox, butthey represent more recently received messages and are thus representedby the priority-colored icons (e.g., red). In FIG. 10B, the map on theNAVI display 20 changes scale to zoom in and show the current locationicon 196 in the center of the map and the previously viewed locationicons 198 and 200 together with the newly received location icons 202and 204. In another embodiment, there is time received information(e.g., time stamps) displayed in proximity to the corresponding icons198-204 on the maps displayed on the NAVI display 20. The time receivedinformation can comprise the time of receipt of the SMS message thatcontains address information that is displayed to the user via the icons198-204. In another embodiment, the time received information caninclude the date of receipt as well. In yet another embodiment, thesetimes can be used to limit the number of icons shown on the NAVI display20, by allowing only addresses that were contained in messages receivedwithin the last week to appear on the screen.

FIG. 11A is an example of a map of the current vehicle position withenumerated colored location icons corresponding to addresses in receivedSMS messages displayed in the NAVI Inbox on the NAVI display 20according to an embodiment of the system and method. The map shown inFIG. 11A is similar to the map shown in FIG. 10A, with the addition ofenumerated location icons in FIG. 11A. The numbers illustrated are inthe center of the diamond shaped location icons 210, 212, 214, and 216,but can appear in other formats too, such as smaller numerals located atthe left or right portion of the location icons. The numerals appearingon the icons correspond to the enumerated SMS messages listed in theNAVI Inbox, as illustrated in FIG. 11B. The shape of these locationicons can vary as well (e.g., square or circles) or in anotherembodiment, the icons can comprise a complex shape that correspond to atype of business of the particular extracted address (e.g., a gas pumpfor a gas station). Icons 210 and 216 represent initially viewed iconsand comprise the second color or non-priority color (e.g., grey), whileicons 212 and 214 represent newly received icons and comprise the firstcolor or priority color (e.g., red), as discussed with respect to FIGS.10A and 10B, above.

FIG. 11B illustrates the NAVI inbox that can be displayed on the NAVIdisplay screen 20 when SMS messages are retrieved from the wirelessdevice 12 according to an embodiment of the system and method. Themessage listings are enumerated and are shown in descending order andany newly received, unviewed message is marked as “NEW.” As will bediscussed in further detail with respect to FIG. 17A-18B, the user canroute to a destination address displayed on the map as an icon, shown inthe NAVI Address Book, or shown in the NAVI Inbox, as well as place aphone call to the corresponding phone number for any of these displayeditems. One skilled in the art will recognize that the messages can belisted in other ways (such as in ascending order) and the unreadmessages can be demarked by other methods (such as being listed in boldfont or listed in a second colored font).

The intelligent text recognition system mentioned above comprises analgorithm or method used to extract address and phone number data from amessage, shown in overview form in the flow diagram of FIG. 12. Thenavigational data extracted from each message may then be sent to theNAVI 16 for routing or to the HFT 14 for calling. In an embodiment ofthe system and method, the intelligent text recognition system firstreceives an SMS message from a wireless telephone or mobile device 12 instep 220, after the vehicle ignition has been set to the “ON” positionin step 218. Polling of the wireless device 12 is periodically carriedout by the HFT 14 to retrieve newly received SMS messages from thewireless device 12 (see FIGS. 4 and 5A-E; see also, related discussionthereto). The algorithm then proceeds to parse through the message todetermine if a telephone number is detected by identifying phone numberpatterns, as in step 222. If a phone number is detected, a call buttonon the NAVI display 20 is enabled and the phone number is stored inmemory in step 224. The algorithm then proceeds to step 226 to determineif additional phone numbers are present in the SMS message. If so, step222 is repeated until no additional phone numbers are present in the SMSmessage and the detected phone number strings are subsequentlydisregarded in step 228. The SMS message is then parsed through again todetermine if an address is detected in step 45. If an address isdetected, the route button on the NAVI display 20 is enabled and theaddress is stored in memory in step 232. The algorithm then proceeds tostep 234 to determine if additional addresses are present in the SMSmessage.

FIG. 13 is a flow diagram illustrating a more detailed algorithm for anexemplary method of detecting the phone number data in an SMS message.The method corresponds to a more detailed breakdown of the algorithmthat may be used in step 222 of FIG. 12. The algorithm starts at block238. Entry point F, as shown in block 236, is provided to allow otherportions of the routine to return to this starting point. In step 238, aparser checks each character string in the SMS message and determines instep 240 if there are additional character strings to analyze. If not,the algorithm ends in step 242. If there are more character strings toanalyze, the current string is analyzed to determine if the string is a7-digit numeric string in step 246. If so, the 7-digit string is savedas a 7-digit phone number in memory in step 248 and the parser moves tothe next character string in step 254. The algorithm then returns tostep 238 via entry point F, to analyze the next character string. If thestring is not a 7-digit numeric string, the string is analyzed todetermine if it is a 10-digit string in step 250. If the string is 10digits long, then the string is stored in memory in step 252, and theparser moves to the next character string step 254. The algorithm thenreturns to step 238 via entry point F, to analyze the next characterstring. If the string is not 10 digits long, the string is analyzed instep 260 to determine if it is an 8-character string matching the formatof ###*#### (e.g., 555-1212), where “#” represents a number and “*”represents a “-”, “.”, “(”, “)”, or a space. If the string matches the8-character format, the 7 numeric digits are extracted and stored inmemory in step 262, and the parser moves to the next character stringstep 254. The algorithm then returns to step 238 via entry point F, toanalyze the next character string. If the string does not match the8-character format, the string is analyzed for the 12-character formatof ###*###*#### (e.g., 213-555-1212) in step 264. If the string matchesthe 12-character format, the 10 numeric digits are extracted from thecharacter string and are stored in memory in step 264, and the parsermoves to the next character string step 274. If the string does notmatch the 12-character format, the string is analyzed for the13-character format of *###*###*#### (e.g., (213)555-1212) in step 266.If the string matches the 13-character format, the 10 numeric digits areextracted from the character string and are stored in memory in step268, and the parser moves to the next character string step 274. If thestring does not match the 13-character format, the string is analyzedfor the 14-character format of *###**###*#### (e.g., (213)555-1212) instep 270. If the string matches the 14-character format, the 10 numericdigits are extracted from the character string and are stored in memoryin step 272, and the parser moves to the next character string step 274.If there is no match, the parser simply moves to the next characterstring in step 274. The process is repeated for each character stringencountered. It should be appreciated that other algorithms may be usedfor extracting a phone number from a text string and the above describedsteps may be performed in varying order from that presented in FIG. 13.

FIGS. 14A-E comprise different portions of a flow diagram illustrating amore detailed algorithm for an exemplary method of detecting the addressdata in an SMS message and corresponds to a more detailed breakdown ofthe algorithm that may be used in step 230 of FIG. 12. In an exemplaryembodiment of the system and method, the intelligent text recognitionsystem keeps a working copy of the SMS message used during the processof extracting each address. FIG. 14A shows a portion of the exemplaryalgorithm for extracting a zip code from the SMS message. Once the phonenumbers are detected in the SMS message (as shown in the exemplarymethod described above), the phone number strings and any characterstrings containing phone numbers are deleted from the working SMSmessage, in step 276. Thus, the parser does not need to repeat theprocess for strings already known to be a phone number. Entry point K,as shown in block 278, is provided to allow other portions of theroutine to return to this starting point. A parser moves to eachcharacter string in step 278, starting from the end of the stringworking backwards. Next, in step 280, the algorithm determines if thereare additional character strings to analyze. If not, the algorithm endsin step 282. It should be appreciated that while the exemplary algorithmshown parses backwards through the SMS message to speed up the processof detecting zip codes that are generally located at the end of anaddress, the system and method is not limited to parsing backwards. Ifthere are more character strings to analyze, the current string isanalyzed to determine if the string is a 5-digit zip code in step 284.If the current string is a zip code, the 5-digit zip code is saved inmemory as a backup in step 286. The parser then moves back one characterstring for analysis in step 288 and the algorithm proceeds to step 294via entry point G at block 290. If the string is not a zip code, thealgorithm proceeds to step 294 via entry point G at block 290, where thecharacter string is analyzed to determine if it is a state.

FIG. 14B shows a portion of the exemplary algorithm for extracting astate from the SMS message. Entry point G, as shown in block 290, isprovided to allow other portions of the routine to return to thisstarting point. In step 294, the current string is analyzed to determineif it is a state by comparing the character string to a list of statesstored in memory to determine if there is a match. If the current stringis a state, the state is saved in memory in step 296. A city list isalso stored in memory, but is limited to only those cities within thedetected state in step 298. The parser moves back one character stringfor analysis in step 300, and proceeds to step 312 via entry point H atblock 310. If the string is not a state, the algorithm determines instep 302 if a zip code was previously stored in the preceding step 286.If a zip code was stored, the state associated with the stored zip codeis stored in memory in step 304. The city list is then limited to onlythose cities within the state correlating with the zip code in step 308and the algorithm proceeds to step 312 via entry point H at block 310.If a zip code was not in fact previously stored, then in step 306 thecity list is limited to only those cities within the state where thevehicle is currently located. The vehicle location is determined via theGPS receiver (not shown) connected to the NAVI 16. The algorithm thenproceeds to step 312 to extract a city via entry point H at block 310.

FIG. 14C shows the portion of the exemplary algorithm for extracting acity from the SMS message. Entry point H, as shown in block 310, isprovided to allow other portions of the routine to return to thisstarting point. In step 312, the current string is analyzed to determineif it is a city by comparing the character string to a limited list ofcities stored in memory to determine if there is a match. If the currentstring is a city in the list, the city is saved in memory in step 314.There is also a street list stored in memory that is limited to onlythose streets within the detected city in step 316. The parser movesback one character string for analysis in step 318, and the algorithmproceeds to step 330 to extract a street name via entry point I at block328. If the string is not a city, the algorithm determines in step 320if a zip code was stored in the preceding steps. If a zip code wasstored, the city associated with the stored zip code is stored in memoryin step 322. The street list is then limited to only those streetswithin the city in step 326 and the algorithm proceeds to step 330 inFIG. 14 d via entry point I at block 328. If a zip code was not stored,the street list is limited to only those streets within the city wherethe vehicle is located in step 324. The vehicle location is determinedvia GPS from the NAVI 16 on the vehicle. The algorithm then proceeds tostep 330 to extract a street name via entry point I at block 328.

FIG. 14D shows the portion of the exemplary algorithm for extracting astreet name from the SMS message. Entry point I, shown in block 328, andentry point L, shown in block 332, are provided to allow other portionsof the routine to return to step 330 as a starting point. In step 330,an internal counter in memory is incremented in order to keep a count ofhow many strings have been compared to the limited street list. Theprocess of comparing street names to the limited list is performed fourtimes to properly identify street address information in the exemplaryembodiment, as address information may contain an apartment or suitedesignator, road type, direction, or other information (e.g., 400 SouthMain Street, Suite 100, Any Town, CA 90001). It should be appreciatedthat the system and method is not limited to matching street namessolely containing four strings, but may cycle through any number ofstrings to attempt to extract a complete street name. In step 334, thecurrent string is analyzed to determine if it is numeric in nature, suchas would be the case if the address string being analyzed contains asuite number. If the string is numeric, the parser is moved back onecharacter string in step 336 and the algorithm continues in step 330. Ifthe string is not numeric, the current string is analyzed in step 338 todetermine if it is a street name by comparing the character string tothe limited list of streets stored in memory to determine if there is amatch. If the current string is a street name in the list, the streetname is saved in memory in step 340. A street number list stored inmemory is limited to only those street numbers located on the detectedstreet name in step 344. The parser moves back one character string foranalysis in step 348 and the algorithm proceeds to step 354 (see FIG.14E) for extraction of the street number via entry point J at block 352.If the current string does not match a street name stored in the limitedstreet name list, then the parser moves back one-character string instep 342 and the value of the internal counter is checked to determineif four strings have been compared yet in step 346. If the value of theincremental counter is four, then the street name cannot be found in theSMS message in step 350, and the algorithm proceeds back to step 278(see FIG. 14A) via entry point K at block 292.

FIG. 14E shows the portion of the exemplary algorithm for extracting astreet number from the SMS message. Entry point J, as shown in block352, is provided to allow other portions of the routine to return tothis starting point. In step 354, the current string is analyzed todetermine if it is a street direction indicator such as North, South,etc. by matching the string against a direction table stored in memory.If the current string is a direction indicator, the indicator is storedin memory in step 356, the parser moves back one character string instep 358, and the algorithm proceeds to step 360. If a directionindicator is not matched, the current string is analyzed in step 360 todetermine if it is a street number by comparing the character string tothe limited list of street numbers stored in memory to determine ifthere is a match. If the current string is a street number in the list,the street number is saved in memory in step 362 and the entire addressis sent to the NAVI 16 for possible routing in step 366. The parsermoves back one character string for further analysis in step 370, wherethe process is repeated in step 278 (see FIG. 14A) via entry point K atblock 292, to determine if there are additional addresses in the SMSmessage. If the current string does not match a street number in thelimited street number list, then the parser moves back one characterstring for further analysis in step 364 and the algorithm proceeds tostep 368 to determine if the internal variable has reached four strings.If four strings have been compared, the algorithm returns to step 278(see FIG. 14A) to determine if there are additional addresses forextraction via entry point K at block 292. If four strings have not yetbeen compared, the algorithm proceeds back to step 330 to compareadditional strings via entry point L at block 332. In anotherembodiment, the order of the above steps in FIGS. 14A-E can be alteredso that the system looks for all state and zip code information in theSMS message first. Then the algorithm uses the detected characterstrings as a basis for looking for address information, thereby reducingthe number of iterations the system would otherwise have to perform.

FIGS. 15A-B illustrate different portions of a flow diagram of analgorithm for an exemplary method of routing to a destination containedin an SMS message. In FIG. 15A, a received SMS message will be displayedon the NAVI display 20 in step 372. Entry point N, as shown in block371, is provided to allow other portions of the routine to return tothis starting point. Once the intelligent text recognition systemdetects an address in the received SMS message, a route selection iconor button (see FIG. 12) will be enabled via the HMI (not shown) forselection by the user. If the user makes a selection to route to anaddress in step 374, the algorithm checks to see if there is one addressor multiple addresses to present to the user in step 376. If the userhas not made a routing selection in step 376, the system determines ifthe user has input a selection (via the HMI) for the NAVI to make acall, read a message, or optionally, to delete a message in steps 380,384, or 387, respectively. The method then returns to step 374 todetermine if “Route” has been selected by the user.

Continuing with step 376, if there is only one address to present to theuser, the address extracted from the SMS message is displayed to theuser in step 382 and the HMI prompts the user as to whether the userwants to edit (step 386), route (step 384), or cancel (step 390) therequested routing to the displayed address. The method proceeds througha series of steps to determine if the user has selected any of theseavailable commands via the HMI in steps 386-390. If the user selected“Edit,” in step 386, the user edits the address data in step 388 and themethod returns to step 382 to display the newly edited address. If“Edit” is not selected in step 386, but instead “Route” is selected instep 384, the NAVI 16 will calculate and display a route to thepresented address in step 385. If “Route” has not been selected by theuser in step 384 and “Cancel” has been selected in step 390, thealgorithm returns to step 372 and the SMS message is once againdisplayed in the NAVI display 20. In another embodiment, the addressdisplayed on the NAVI display 20 in step 382 will not be editable by theuser. Thus, the user can either “Route” to the address or “Cancel” therequested routing, thereby simplifying the algorithm by the eliminationof steps 386 and 388.

If in step 376 there are multiple addresses to present to the user, thealgorithm proceeds to step 392 (see FIG. 15B) via entry point M at block378. The method prompts the user via the HMI as to whether she wants toview the next extracted address (step 394), edit the current address(step 398), route to the current address (step 402), or cancel (step406) the routing to the displayed address. The method determines if theuser has selected any of these options via the HMI in steps 394, 398,402, and 406. If the user selects “Next” in step 394, the HMI displaysthe next address extracted from the SMS message in step 396 and returnsto step 392. If the user selects “Edit” in step 398, the HMI allows forediting of the address data in step 400 and returns to step 392 todisplay the newly edited address in the NAVI display 20. If “Edit” isnot selected in step 398, but instead “Route” is selected in step 402,the NAVI 16 will calculate and display a route to the presented addressin step 404. If “Route” is not selected in step 402 and “Cancel” isselected in step 406, the algorithm returns to step 373 via entry pointN at block 372, and the SMS message is once again displayed on the NAVIdisplay 20. In another embodiment, all of the addresses displayed on theNAVI display 20 in step 392 will be shown in a list, thereby allowingthe user to directly choose the address of interest. Again, the addressdisplayed on the NAVI display 20 in step will not be editable by theuser and so the user can either “Route” to the address or “Cancel” therequested routing, thereby simplifying the algorithm by the eliminationof steps 398 and 400.

FIGS. 16A-B comprise different portions of a flow diagram illustratingan algorithm for an exemplary method of calling a telephone numbercontained in an SMS message. In FIG. 16A, a received SMS message isdisplayed on the NAVI display 20 in step 408. Entry point P, as shown inblock 410, is provided to allow other portions of the routine to returnto this starting point. Once the intelligent text recognition systemdetects a telephone number in the received SMS message (see step 222 inFIG. 12), a call selection icon or button will be enabled via the HMIfor selection by the user in step 224 (see FIG. 12). Returning now tothe flow diagram in FIG. 16A, if the user selects the “Call” command instep 412, the method then checks if there is one phone number ormultiple phone numbers to present to the user in step 414. If the userhas not selected the “Call” command in step 412, then the methodproceeds through a series of steps to determine if she has selected toroute to an address (step 418), read a message (step 422), oroptionally, to delete a message (step 428) prior to the method returningto step 412, to determine if “Call” has been selected via the HMI.Continuing with step 414, if there is only one phone number to presentto the user, the phone number extracted from the SMS message isdisplayed in step 420 and the HMI prompts the user to determine if shewants to edit (step 424), call (step 430), or cancel (step 434) thetelephone call to the displayed phone number. Next, the methoddetermines if the user has selected any of these options via the HMI insteps 424, 430, and 434. If the user selects “Edit” in step 424, themethod allows the phone number to be edited in step 426 and returns tostep 412 to display the newly edited phone number on the NAVI display20. If “Edit” is not selected in step 424, but instead “Call” isselected in step 430, a call will be placed to the presented phonenumber via the HFT 14 in step 432 and the method returns to step 408 todisplay the SMS message. If “Call” is not selected in step 430 and“Cancel” is selected in step 434, the method returns to step 408 and theSMS message is once again displayed on the NAVI display 20. In anotherembodiment, the phone number shown on the NAVI display 20 at step 420will not be editable by the user. Thus, the user can either “Call” thephone number shown on the NAVI display 20 or “Cancel” the requestedphone call, thereby simplifying the algorithm by the elimination ofsteps 424 and 426.

If in step 414, there are multiple phone numbers to present to the user,the algorithm proceeds to step 436 (see FIG. 16B) via entry point O atblock 416. In FIG. 16B, the method prompts the user via the HMI, todetermine if she wants to view the next phone number in the SMS message(step 438), edit the current phone number (step 442), call the currentphone number (step 446), or cancel the call (step 450) request to thedisplayed phone number. The method determines if the user has selectedany of these options via the HMI in steps 438, 442, 446, and 450. If theuser selects “Next” in step 438, the HMI displays the next phone numberextracted from the SMS message in step 440 and then returns to step 436.If the user selects “Edit” in step 442, the method allows the phonenumber to be edited in step 444 and returns to step 436 to display thenewly edited phone number. If “Edit” is not selected, but instead “Call”is selected, a call will be placed the presented phone number via theHFT 14 in step 448, and the algorithm returns to step 408 to display theSMS message on the NAVI display 20. If “Call” is not selected in step446 and “Cancel” is selected in step 450, the algorithm returns to step408 via entry point P at block 410, and the SMS message is once againdisplayed on the NAVI display 20.

FIGS. 17A-B show exemplary NAVI display screen images for a navigationalsystem according to an embodiment of the system and method. In FIG. 17A,a screen 452 shows the screen image on the NAVI display 20 when an SMSmessage is received. The screen 452 shows a map with the user's currentlocation encircled. The received message is indicated by the envelopeicon in the upper left of the screen 452. The user may choose to getmore information via the HMI, that displays screen 456 with a menu ofavailable user prompts on the NAVI display 20. The user may then select“Messages” by touching the appropriate portion of the screen 456 to viewa list of received messages that are next displayed in screen 454. Theuser then selects the SMS message to view by selecting the messagenumber. Screen 460 is then displayed listing the text of the SMS messagein the top half of the screen image and a menu in the bottom half of thescreen. Entry point R, as shown in block 458, is provided to allow otherportions of the routine to return to screen 460. The menu in screen 460allows the user the option to read the message aloud via the TTSsoftware component, reply to the SMS message, route to an addressextracted from the SMS message, or call a telephone number extractedfrom the SMS message. If the user selects “Route” or “Call,” the screentransitions to either screen 464 or screen 466, respectively, via entrypoint Q at block 462. If the “Reply” function is selected by the userthe system shows preset messages from which the user can select from toreply to the sender of the SMS text message.

In another embodiment, the arrangement of the text message and menuoptions can vary, such as the menu occupying the top portion of thescreen and the text portion of the SMS message occupying the bottomportion of the screen image. The SMS message may be displayed in full ormay be truncated depending on available space on the screen. Iftruncated, the HMI may allow for scrolling of the SMS message to allownon-visible portions to be viewed on the NAVI display 20. In yet anotherembodiment, the “Route” and “Call” selections will only be enabled whenan address and phone number, respectively, are extracted from the SMSmessage.

Turning now to FIG. 17B, entry point Q, as shown in block 462, isprovided to allow other screens to change to screens 464 and 466. If theuser selects “Route,” the HMI displays screen 464 to confirm the correctaddress that the user wishes to route to. Once confirmed, a route iscalculated and screen 468 will be displayed. As discussed in referenceto FIG. 15B, if multiple addresses are extracted from the SMS message,the “Next” selection will be enabled so that the user can view andselect another address that was extracted from the received SMS message.If the user once again selects “Route,” a route is calculated from thecurrent location of the vehicle to the address that was extracted andselected by the user, as shown in screen 468. A progress bar informs theuser how much longer it will be for the system to calculate the routerequested. On completion, screen 470 shows the calculated route on theNAVI display 20, as the NAVI 16 directs the user to the desireddestination address.

If instead of selecting “Route” the user selects “Call” at screen 460,the HMI displays screen 466 to confirm the correct phone number the userwishes to call. After the user confirms she wants to place a call to thedisplayed phone number, the system makes the call. The display 20 thentransitions back to displaying the screen 460 (see FIG. 17A) via entrypoint R, at block 458. The screen shows the text of the received SMSmessage on the top portion of the screen and the menu on the bottom halfof the screen. As discussed in reference to FIG. 16B, if multiple phonenumbers are extracted from the SMS message, the “Next” selection will beenabled in step 466. If the user once again selects “Call,” the phonenumber to be called is sent to the HFT 14 and a call is generated to theselected phone number that was extracted from the incoming SMS message.The screen then transitions back to viewing the SMS message as shown inscreen 460.

FIGS. 18A-B show exemplary NAVI display screen images for a navigationalsystem according to another embodiment of the system and method. In FIG.18A, a screen 472 shows the screen image on the NAVI display 20, when anSMS message is received. The screen 452 shows a map with the user'scurrent location encircled. The received message is indicated by theenvelope icon in the upper left of the screen 472. The user may chooseto get more information via the HMI, which displays screen 476 with amenu of available user prompts on the NAVI display 20. If the userwishes to obtain POI information for routing purposes, the user may thenselect “Point of Interest” by touching the appropriate portion of thescreen 476. The NAVI display 20 then transitions to screen 474 where theuser enters the place name for which she wishes to get navigation data,via the HMI. The user may enter information such as company name, city,state, longitude, latitude, zip code, or the like using the alphabetwheel and “Delete/Space” button that appear on the screen 474. In otherembodiments, information may be entered into the HMI via other methodssuch as an alphanumeric keypad or via the user speaking aloud thecharacters into a microphone in the vehicle (wherein a VR softwarecomponent is utilized). If a specific location is not selected by theuser, the SMS request message 40 (see FIG. 3) may be generated usinglocation information retrieved via the GPS receiver (not shown)connected to the NAVI 16. It should be appreciated that a subject, suchas restaurants, or other POI indicators may alternately be entered toretrieve POI navigational data on the NAVI 16. Once the entry is enteredby the user, an SMS message addressed to a POI SMS message serviceprovider will be generated and transmitted via a wireless Bluetoothconnection to the mobile device 12 (see FIGS. 2 and 3).

The NAVI display 20 transitions to screen 478 and shows the user themessage transmission progress as the SMS message is transmitted over thewireless network 22 (e.g., a GSM or CDMA network). When an SMS messageresponse is received from the POI SMS message service provider (such asa CSC service provider like Google), the screen transitions to screen482 (see FIG. 18B) via entry point T at block 480. The screen 482 liststhe text of the SMS message and allows the user the option of having thesystem read aloud the received message via the TTS software component(not shown), or optionally, to delete the SMS message (not shown), routeto an address extracted from the SMS message, or call a telephone numberextracted from the SMS message. The SMS message may be displayed in fullor may be truncated depending on available space. If truncated, the HMImay allow for scrolling of the SMS message to view the non-visibleportions of the message. When the SMS message is sent from a CSC serviceprovider (e.g., in response to a Point of Interest request asillustrated in FIG. 18A), the “Reply” option is disabled (or grayed out)as in screen 482. This is in contrast to the personal SMS messagereceived from a person such as a friend or associate (as was illustratedin FIG. 17A), where the user may wish to reply to the sender of the SMSmessage by selecting the “Reply” feature shown in screen 460, whichallows the user to select a preset message. The system enables ordisables the “Reply” function by determining if the sender's phonenumber in the SMS message is from a CSC provider or an individual.

In another embodiment, the “Route” and “Call” selections are onlyenabled when an address and phone number, respectively, are extractedfrom the SMS message. If the user selects “Route,” the NAVI display 20shows the screen 486 for the user to confirm the correct address to berouted. As discussed in reference to FIG. 15B, if multiple addresses areextracted from the SMS message, the “Next” selection icon or button willbe enabled on the HMI. Returning now to FIG. 18B, if the user once againselects “Route,” a route is calculated from the current location of thevehicle to the extracted and selected POI address. A progress barinforms the user how much longer it will be for the system to calculatethe route requested as shown on screen 484. On completion, screen 488shows the calculated route to the desired POI on the NAVI display 20, asthe NAVI 16 directs the user to the desired destination address. In analternate embodiment, the NAVI 16 may automatically route to the addresslocated in the received SMS message rather than requiring selection bythe user. A POI icon may be used to indicate the location of theextracted address on the routing map displayed. Additionally, the NAVI16 may automatically store the extracted addresses and/or phone numbersin an address book stored on the vehicle. In a variation of thisembodiment, a timer may be implemented in the NAVI 16 such that an errormessage can be displayed if the allotted time expires and an SMSresponse message has not yet been received from the SMS message serviceprovider. In another embodiment, the user may request information otherthan address and phone number information from the service provider bythe use of additional available selections in screen 476. Both thewireless carrier and the service providers will then return otherrequested information such as “Weather”, “Business News”, “Movie ShowTimes,” etc., by the system sending a correctly coded text message. Inthis way, the user will be able to view “Headline News” as an SMS textmessage in her vehicle in a similar fashion as with personal textmessages received from a friend.

Having thus described a preferred embodiment of a method and system forutilizing a wireless messaging service to obtain data for navigationalrouting, placing telephone calls and sending email messages from anin-vehicle navigation system, it should be apparent to those skilled inthe art that certain advantages of the described method and system havebeen achieved. It should also be appreciated that various modifications,adaptations, and alternative embodiments thereof may be made within thescope and spirit of the present system and method. For example,reception of navigational data via an SMS message has been illustrated,but it should be apparent that the inventive concepts described abovewould be equally applicable to other messaging services such as SimpleMail Transfer Protocol over Transmission Control Protocol and theInternet Protocol, Enhanced Messaging Service, Multimedia MessagingService, or the like. Additionally, it should be apparent that theinventive concepts described above would be equally applicable toextracting navigational data from messages outgoing from the vehicle aswell as incoming to the vehicle. Further, it should be apparent that thesystem could comprise both a TTS engine and a VR software component sothe extracted navigational data could be read aloud to the user, whileuser input and message composition could be provided by the userspeaking aloud her choices.
